vTo all .whom `i?? may concern:

Be itknown that I, WILLIAM F: SCHULTZ,

a citizen of the yUnited States, residing at Cincinnati, in the county of Hamiltonand State of Ohio, have inventedcertainfnew and useful Improvementsin Safe'and Vault Construction, of which the following is a specifi- V vantages of which will be hereinafterV set ries of separated columns of dis forth, reference being-had to theanneXed drawings wherein,.for the purposes of illustration, the invention is shown asapplie'd to.

should a hole be burned or drilled through a :safe door.

In. said drawings: Figure 1 is a horizontal sectional view, on the line `1---1 of Fig. 2; Fig. 2 a front elevation*V of a portion of the 'safe and door, a part of the latter beingzu shown in section; Figs. 3 and 4 detail sec-1` tional views of` amodifiedarrangement; and. Fig. 5 a sectional view of one of the laminated disks employed in the structure.

The main object of the invention is to provide a structure which is at once both burglar and fire proof, the constructionV being such that it is not affected by an electric arc nclllwill withstand penetration by the use of r1 s. i

As before noted, the invention is shown in connection with a safe door, but it is'to be understood that it is not to be limited thereto, the invention being applicable to safe and vault work generally.

In Figs. 1 and 2 I have shown the invention as 'applied to a safe door though, of course, it will be readily appreciated that it may be used in`any other part of the safe or vault construction. In said figures, A denotes the outer face of the door, preferably made of cast steel and having formed therewith the side faces `or walls B.

C indicates the inner face of the door, preferably formed of Bessemer steel and bolted to the inner iianges of they side faces or walls B. The door is thus made hollow or provided with an inclosed chamber, which is filled with a suitable non-conducting or insulating material D, such for instance as a hard, insulating cement. Within this body of cement, and preferably adjacent to. the outer face or member A, are arranged'a number of disks E, said disks by preference being arranged in two layers, each comising a sewith the specification'of Letters Patent.

SAFE'AND vAULT CONSTRUCTION.

Patented Marche, 190e.`

Adisks ofeaeh columnseparated from eac other. Preferably, `the columns of the `two llayers will :stand inra staggered relation to eachother,` the distance between -the proxi- 4mate `edgesof the diskscomprisin the outer-` most columns being approximate ,yequal to the width of the -disks comprising the-inner- `most ilayer, so that substantiallyitheentire inner face of `the member A may be said to bebacked-'up-by a seriesof independent-insu-` lated disks.

,Aswill be seen upon reference to Figs. 1 and 2, the disks are separated from-each other and from the door or framing, so that the outer casing `the.disks,rloy reason ofttheir insulated relation, would prevent the passage ofcu-rrent from'on'e'ito the other, thusv afford- `the electric arc.

" The f disks alsoi perform another highly-limportant function, in.y that they reventtthe drilling of the structure. `As wi l be readily appreciated, a drill, after passing through the outerface A, will come into contact with the face of one of the disks; or against the edge of one o r more of the disks. If against the face, the disk will turn and further penetration of the drill is thereby prevented. If between the disks, or against the edge of one or more, the drill will be broken or shattered; .To render the disks more edective against the action of the drill, they will preferably be ing A,protection againstthe 4burning effect of laminated or formed of alternate layers of v steel and iron, as indicated by a and b, Fig. 5.

In Figs. 3 and L1 I have illustrated a slightly modified arrangement, three layers of disks 1, 2 and 3, being shown as embedded in the cement. The outermost layer, 1, in this instance is shown as resting against the. inner' face ofthe outside member F. The layers 1 and 2 bear the same relation to each other as in the construction heretofore described, while the third or innermost layer, 3, stands in line with the substantially diamond-shaped spaces left between the outer and intermediate layers. This construction will edectually prevent the passage of even a small drill.v As inthe former case, the

. disks are insulated. from each other. n

Having thus described my invention, what' I claim is:

1. In a structure of the class specified, the combination of a wall; a body of insulating material in rear thereof; and a series of sepam rear thereof, the axis of each disk standing at approximately' right angles to the face ofv the Wall.

3. In a structure of the class specified, the combination of a Wall; a backing of insulating material; and a series of independent disks embedded in said material, the axis of each disk standing at approximately right angles to the Wall.

4. In a structure of the class specified, the combination of a Wall; a backing of insulating material; and tWo layers of disks embedded in said material, the disks being `independent of each other and of the Wall and having their axes at substantially7 right angles to the Wall. l

5. In a structure of the class specified, the combination of a Wall; a backing of insulating material; and two layersV of separated disks mounted therein, each layer of disks being composed of separated vertical columns, the columns of one layer being staggered With relation to those of the other the axes of the disks being at substantially right angles to the face ofthe Wall.

6. In a structure of the class specified, the combination of a Wall; a backing of insulating material; and a plurality of layers of disks mounted therein, the disks of the various layers bearing a staggered relation, and each disk being insulated from the Wall and the other disks by the insulating material each disk having its axis at substantially right angles to the face ofthe Wall.

7. In a structure of the class specified, the combination of a wall; a body of hard insulating cement in rear thereof; and a series of separated metallic members mounted in said cement, said members being free to rotate under the action of a drill.

8. In combination with an outer steel casting; a closure for the rear portion thereof; a filling of insulating cement placed within the chamber formed by said members; and a series of metallic disks embedded in the cement, the disks being separated from one another, and the axis of each disk standing at approximately right angles to the face of the outer casting.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
